I have a partridge rock, the gender of which I am not sure. The feathering, shape, and vent size make me think it is a cockerel. But the comb size, spur size, and the fact that my roo is trying to get frisky with him/her, makes me think it's a lady chicken. I am definately noticing saddle and sickle feathers But the comb look soooo small when compared to this Phoenix Cockerel of the SAME AGE. They are both 4 months old-----The Phoenix is crowing, mating, and strutting his stuff, but the rock is silent, has not much to show, and is GETTING MATED. If the rock is a cock, than these two breeds must mature at completely different times. I have always used the phoenix to base the gender of the rock off of. I guess I gotta look more into the feathering.... What do y'all think?
